STUMP-PULLER.

SPECIFICATION forming part of Letters Patent No. 368,216, dated August16, 1887.

Application filed June 14, 1887. Serial No. 241,289. (No model.)

To all whom it may concern:

Be it known that I, CHARLES KRUEGER, a citizen of the United States,residing at \Vausau, in the county of Marathon and State of \Visconsin,have invented a new and useful Improvement in Stump-Pullers, of whichthe following is a specification.

My invention relates to improvements in stump-extractors; and itconsists in certain novel features, hereinafter described and claimed.

In the accompanying drawings, Figure l is a perspective view of myimproved stump-extractor. Fig. 2 is a vertical section of the same. Fig.3 is a detail view of the spool and supporting-plate for the end of thesweep.

Referring to the drawings by letter, A A A designate thesupporting-legs, which are braced by suitable beams, B, as shown. Therear legs, A A are provided with rollers O at their lower ends, whilethe front leg, A, is provided at its lower end with a shoe, D, whichallows it to be drawn over the ground, but at the same time prevents itssinking into the same when the device is in operative position. At thetop of the tripod formed by the legs A A A I provide the plate E, havingthe sleeve F depending from its under side. This sleeve F has therecesses G in its outer side, in which the ends of the legs are secured.The edge of the plate E projects slightly past the side of the sleeve F,and is engaged by a series of lips or plates, G, secured to the castingH, to which the end of the sweep or operating-lever I is secured. To theunder side of the sweep, at the upper end of the same, I secure a plate,J, which projects .under the edge of the plate E and aids the plates Gin holding the sweep thereto and giving it a smooth easy motion. Thecasting H has a central angular opening, through which the upper angularend of the shaft K projects. The central portion of this shaft K iscylindrical, and its lower end is screw-threaded and works th rough ascrew-threaded sleeve, L, set in a cross-beam, M, secured to thebracebeams B.

At a point, N, on the rear side of the front leg, A, 1 Secure the pulleyO. The operatingrope P has one end secured to the leg A a short distancebelow the pulley O, and after passing over said pulley has its other endsecured to the shaft K.

Q designates a pulley loosely mounted on the rope P between the pulley Oand the end of the rope, and provided with a hook, R, to engage thestump.

From the foregoing description, taken in connection with theaccompanying drawings,

' it is thought the operation of my device will be readily understood.

It will be observed that when the shaft K is revolved it will rise,owing to the screwthreadcd construction shown and described, therebycausing the operating-rope to wind smoothly and evenly upon the same andpreserving an even and regular tension on said rope.

Having thus described my invention, what I claim, and desire to secureby Letters Patent, is-

1. The combination of the supportinglegs, the sweep, the vertical shaftextending through the top of the legs and the sweep, and adapted to risetherethrough when rotated thereby, the rope having one end secured tothe shaft and its other end to the rear side of one of the legs, itsintermediate portion passing around a pulley, O, secured to said leg,and a hook, R, carried by a pulley loosely mounted on the rope,substantially as set forth.

2. The combination of the supporting-legs, the plate E at the top of thesame having the depending sleeve F, the sweep, the casting H, to whichthe sweep is secured, and the plates secured to said casting andengaging the edge of the plate E,and the shaft K and operatingrope, asset forth.

3. The combination of the supporting-legs, the cross-beam having asleeve, L, therein, the sweep, the casting H at the top of the legs, towhich the sweep is secured, provided with an angular opening, and theshaft K, having an upper angular end passing through the angular openingin the casting H, and a lower screw threaded end working in thescrewthreaded sleeve L, substantially as specified.

In testimony that I claim the foregoing as my own I have hereto affixedmy signature in presence of two witnesses.

CHARLES KRUEGER.
